11. the Bamboo

Starting from penetration in the missionary position, the woman slides one leg over her partner's shoulder while he brings up his knee. After a while, she brings down her leg and slides up the other one, both partners repeating the movement on the other side. Each movement is repeated several times.

Plusses
A quite acrobatic position: for the most daring.

Minuses
Limited stimulation possibilities.
Requires a great suppleness of the woman.
